My employer moved all of us to Google Apps. Hangouts is really useful to me, because it allows us to have one-on-one chats, a couple of chat rooms for departments and for specific topics and problems.
I've found some Google Talk apps like Talk.to, gChat and others, but the Windows Phone Store says "This app is no longer published".
Trying to find out more, I've read about Microsoft adding Google Talk integration to Outlook.com (link to article), but this appears to be only for chats and not hangouts doesn't seem to be the case for my phone.
Is there any way to use Google Hangouts on my Windows Phone 8.1 device?
